The lattice parameters, magnetic and Mössbauer spectral properties of PrFe11Ti and PrFe11TiH have been measured between 4.2 and 295K. Both compounds crystallize in the ThMn12-type structure. The insertion of hydrogen in PrFe11Ti anisotropically expands the unit-cell volume by 0.4%. Both compounds are ferromagnetically ordered with Curie temperatures of 547 and 604K, respectively. Between 4.2 and 295K, the easy magnetization direction is within the basal plane along the [100] direction as indicated by the Mössbauer spectra which have been fit with a model taking into account both the binomial distribution of titanium near neighbors of the iron atoms and the basal orientation of the magnetic moments.
